Chronos Twins is an action-adventure game released in Europe on October 12, 2007. It was also released in North America on January 18, 2010 and in Europe on May 14, 2010 as a download for the Nintendo DSi system.[1] The game puts a different perspective on time travel than most games. Instead of revisiting an area in two different times, both screens show the same setting during two eras as gamers explore the land with a present-day hero. Chronos Twins was originally planned for release for Game Boy Advance, but after the rise of the Nintendo DS, the game's development switched to that system.[citation needed] An enhanced version for the Wii console entitled Chronos Twins DX was released in North America as a WiiWare download one week prior to the Nintendo DSi release.[2] It was later released in the PAL region for WiiWare on April 2, 2010.

The player takes on the role of Nec, a member of the Llhedar species, who, because of their psychic abilities and the fact that they never give up until the goal is complete, are well suited for missions such as those in this game. The primary mission of the game is to free the planet Skyla from an alien invasion and the powerful entity known as "Twime." Little is known about Twime; she seems indestructible because of her ability to exist simultaneously in two different times. The player is able to teletransport between the two times by using the "Dual Time," a machine created by the sages of Skyla, the Wise. A secondary objective of the game is to avenge the main character's brother, Nash.[3]
